Question

I am trying to append some strings to a file every 5 seconds but I am having some problems.

My Java code is:

File file = new File("MyFile.txt");

FileWriter outFile = new FileWriter(file);

final PrintWriter out = new PrintWriter(outFile);

new Timer().scheduleAtFixedRate(new TimerTask()
{
    public void run()
    {
        out.println("Test string...");
    }, 0, 5 * 1000);
}

out.close();

but I have noticed that my file is always empty: it doesn’t write anything!

I think my problem is in the TimerTask class but I can’t solve it.

Is there a better way to write a file every N seconds?

Answer 1

timer is run in different thread so the file writer is closed first.
